Is it time to move?• Excess Cost

• Currently incurring server charges for instances 24/7/365, even if they are not actively in use

• Slow Scalability• Requires proactive monitoring, request

submission and manual allocation of additional CPU/storage

• Disaster Recovery• Backups must be run and stored ($$)

just in case• Manual intervention required to re-

route traffic to alternate data center

Is the grass really greener?The “cloud” promises:• Cost

• Infrastructure as code, spin up and down as needed

• Scalability • Monitoring with pre-determined thresholds for auto provisioning

• Disaster Recovery• Opportunity to employ real time failover

Where do we begin?• Moving a small house

via straight, well paved roads, in a sparsely populated area is relatively “easy”.• Transporting a multi-

level structure, via narrow windy streets, is a totally different exercise.

How do we get there?• Before you move, you need to plan your exact

route and drive it once or twice to uncover hidden hazards.

Texas.gov Modernization - Guiding Principles

Architectural Simplicity

Modern Open Source Innovation

Modern User Experience

Service Oriented, Layered & Modular

Automated, Scalable Infrastructure

1. Migrate infrastructure to GovCloud.

2. Migrate OS from Solaris to Linux.

3. Migrate application server from WebLogic to Jboss.

6. Update BPEL services to REST based microservices architecture.

7. Prioritize and modernize applications.

Deloitte Digital to modernize user experience and business process.

4. Migrate database from Oracle to AWS RDS.

5. Modernize batch architecture and operations.

Texas.gov Modernization• What worked• Cloud – Software defined Infrastructure as code• Cloud – SaaS services• Reusable UI library• Microservices - Simplified, lightweight Architecture• Open Source based components• CI/CD pipeline

Texas.gov Modernization• Cloud Challenges• Using Infrastructure as code needs skills and time

• 3-6 months initial ramp up to create mature reusable scripts• Cloud – Not all services are currently available in GovCloud

• More are coming everyday• Security

• Cloud has all the tools needed to build robust security but needs skills and time.
